How To Clear A P1299 Code

Last Updated on by David Jon

The best way to clear a P1299 code is to use an OBD-II scanner. If your car is displaying a P1299 code, it means that the powertrain control module (PCM) has detected a random misfire in one or more of the cylinders. In order to clear the code, you’ll need to fix the underlying problem causing the misfire. If the misfire is due to a faulty spark plug, spark plug wire, or coil, you’ll need to replace the offending part. If the problem is with the fuel injector, you’ll need to clean or replace it. Once you’ve fixed the problem, the P1299 code should clear itself. If the P1299 code persists, it’s possible that there is an issue with the PCM itself. In this case, you’ll need to take your car to a mechanic or dealership for further diagnosis and repair.

What Is A P1299 Code?

A p1299 code is a diagnostic trouble code (DTC) for a loss of communication with the electric throttle control actuator control module (ETACM). If your car has the P1299 code, it means that the powertrain control module (PCM) has detected a leak in the secondary air injection (AIR) system. The secondary air injection system is used to reduce emissions from your car. If you have the P1299 code, it’s important to take your car to a mechanic to get it fixed. The P1299 code can cause your car to run less efficiently and can damage your catalytic converter. In most cases, the P1299 code can be fixed by replacing the secondary air injection system. However, in some cases, the P1299 code can be caused by a more serious problem, such as a blown head gasket. If the P1299 code is caused by a more serious problem, it’s important to get your car fixed as soon as possible to avoid further damage.

Should I Turn Off Overdrive When Clearing a P1299 Code in a Ford F150?

When clearing a P1299 code in a Ford F150, it is not necessary to turn off overdrive. The P1299 code indicates an overheating issue in the cooling system, and disabling overdrive will not directly resolve this problem. It is important to focus on diagnosing and fixing the underlying cause of the code. Ford f150 overdrive explained: keeping overdrive on or off does not affect the clearing of this specific code.

What Causes A P1299 Code?

A p1299 code is caused by an engine misfire.
When your check engine light comes on, it’s never a good sign. If you have a scanner handy, you can plug it into your car and find out what code it’s throwing. P1299 is a fairly common one, and it indicates a problem with your cylinder head temperature sensor. This sensor is responsible for telling your car’s computer how hot or cold the engine is running. If it’s not working properly, your car will run lean, which can cause all sorts of problems. In some cases, it can even cause your engine to overheat. If you’re getting a P1299 code, it’s important to take care of it right away. The good news is, it’s usually a pretty easy fix. You can usually just clean or replace the sensor and be on your way. Of course, as with any car repair, it’s always best to consult a professional if you’re unsure of what to do. But if you’re handy with a wrench and you’re feeling adventurous, fixing a P1299 code is a pretty straightforward process.


How Do You Clear A P1299 Code?

A P1299 code is a generic OBD-II code that indicates a problem with the high pressure relief valve in the turbocharger system. This code may be triggered by a faulty turbocharger, a leak in the turbocharger system, or a problem with the engine’s computer. To clear this code, you will need to diagnose and repair the underlying problem.

What Are The Symptoms Of A P1299 Code?

The p1299 code is a code for a loss of communication between the ECM and the PCM. Symptoms of this code include a check engine light, a loss of power, and a stall.


If your car is displaying a P1299 code, it means that there is a problem with the cylinder head temperature sensor. The first thing you should do is check the sensor itself for any damage or corrosion. If the sensor is damaged, it will need to be replaced. If the sensor is not damaged, the next step is to check the wiring to the sensor for any breaks or damage. If the wiring is damaged, it will need to be repaired or replaced. Once the sensor and wiring are checked and repaired as necessary, the P1299 code should be cleared and the car should run normally. I hope that this explanation has helped to clear up any confusion.
